OpenAjax Alliance held its second interoperability event, this one called “InteropFest 1.0″, during the two months culminating with our face-to-face meeting on September 27. When counting Sun’s contribution using jMaki that happened the next day, contributions came from 15 different members using 20 different Ajax toolkits. Each contribution required that multiple Ajax components within a single Web page passes messages through the OpenAjax Hub 1.0. The list of members and toolkits are listed on the InteropFest 1.0 wiki page. Interoperability certificates were awarded at AJAXWorld to the participating member companies. (See press release.)
